Abstract: Iodine nutrition surveillance of vulnerable population was conducted in 18 cities of Henan Province in 2015. The medians and quartiles of urinary iodine concentration in women of reproductive-age (n=3 318), pregnant women (n=36 366), lactating women (n=4 153), infants <2 years of age (n=1 017), and children aged 8-10 years (n=4 806) were 202.1(124.0, 310.0), 192.4(133.6, 262.4), 168.3(119.1, 248.3), 214.2(156.1, 272.3) and 90.0 (121.8, 285.6) μg/L, respectively. Iodine status of the vulnerable populations was generally regarded as adequate in Henan Province. But the median of urinary iodine concentration of reproductive-age women were slightly above the adequate level. The proportions above iodine adequate level were 26.7% in reproductive-age women, 29.4% in pregnant women and 22.5% in children aged 8-10 years.
